A comparative life cycle assessment of recycled tire rubber applications in sustainable earthquake-resistant construction
Traditional construction practices consume significant energy, emit carbon, and generate waste—prompting a shift towards sustainable earthquake-resistant systems. Nonetheless, a comprehensive life cycle assessment (LCA) of such systems remains scarce. This research bridges the gap by evaluating the environmental impact of repurposing waste tire rubber and polyurethane-coated rubber (PUcR) for cost-efficient seismic isolation. To this aim, a comparative LCA of conventional concrete slabs, natural soil foundations, rubberized concrete (RuC) slabs, rubber-soil layers, and PUcR-soil layers revealed key insights. Firstly, RuC is proven to be more sustainable than conventional concrete. Secondly, integrating 30 % recycled tire rubber in the foundation soil cut energy use by 153.50 MJ/m3 and carbon emissions by 30.75 kg CO2 eq/m3. Thirdly, incorporating 30 % waste PUcR in the foundation soil preserved 227.12 MJ/m3 energy and slashed emissions by 134.76 kg CO2 eq/m3. This underscores the significance of sustainable earthquake-resistant construction approaches and LCA-driven decision-making to bolster conservation and recycling endeavors.
期刊介绍：
The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns.
Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
